To all whom it may concern:

Be it known that I, CHARLES BERNARD, a citizen of the Republic of France, residing at Hericourt, in the Department of Haute Saone, Republic of France, have invented a new and useful Improvement in finding Mechanisms for Cotton-Laps of which the following is a specification.

The present invention relates to a device for catching the end of a cotton-wool lap passing from a scutcher. In machines of this kin the winding up of the lap is. usually effected by an arrangement wherein the workman has to spread out his hands over the lap-roller in order to effect the insertion of the coinmencement of the coil. By this process the workman runs great risk of having his hands caught by the roller. This accident frelquently happens and has very serious resu ts.

The object of the present invention is to obviate these dangers. The arrangement hereinafter described effects the regular coil ing of the lap and prevents the workman from touching the lap-roller with his hands.

Referring to the accom anying drawings, Figure 1 shows a front e evation of the device; Fig. 2, a side elevation thereof in the position of rest with the lap just inserted beneath the lap-roller, but not yet wound" round. Fi 3 shows the device in side olevation in t at osition in which the end of the lap is coils around the lap-roller. Fig. 4 shows the inserted commencement of the lap in the position of Fig. 3. In this case the remaining mechanism has been omitted for greater clearness. Fig. 5 shows the mechanism in the position of rest when the lap has been completely wound up and is ready for taking off.

A perforated and curved sheet-iron plate a is arranged over the winding-rolls I) and the lap-roller c. This sheet-iron late makes it possible to observe the winding of the lap, while it prevents any touching thereof by the hand of the Workman. At both sides of the plate a. there is fixed a support (I for not take place at any moment. The oscillation is therefore effected by the upward motion of the bars f. The supports 9, attached to the bars by means of the adjustable anglepieces it, have at their upper ends, respectively, a horizontal slot. These slots effect the oscillation of the guard-plate by means of the pivots 'i engaging in them, which pivots are secured to the sup iorts k, firmly attached to the rotective plate. The mechanism which e sets the insertion of the lap is attached to the protective plate a. It is composed of the following parts: The shaft 1 revolves in two bearings m, fixed to the edges of the protective plate a, parallel to the axles of the winding-rolls, as well as of the laproller 0. The shaft 1 can oscillate about its axis. The motion is effected by hand by means of the hand-lever n, keyed upon the shaft 1. To each end of the shaft Z is attached a lever 0. Each lever 0 has attached to it a lever p, Figs. 1 and 2. This pair of levers is attached to the crossbar g. This cross bar directly acts upon the lap and serves to push the same in by a motion which is indicated in Fig. 2 by the dot-anddash curve. The outermost point of the stroke of the cross-bar q is sup osed to be at M. Upon the oscillation of t 1e shaft 1 the crossbar g moves in the path indicated, be ing guided by the bars 8, attached to the le vers p. These bars .9 carry the adjustable followers t, which move in contact with the cams r. The bars .9 slide in guiding-sleeves oscillating upon the pivots i.

The a paratus operates as follows: As soon as the lap has been caught and its end appears beneath the lap-roller c, as shown in Fig. 2, the o erative presses down the lever n smartly. his efiects a turnin of the shaft Z, as well as a motion of the two overs o. The cross-bar 9 now effects the motion indicated in Fig. 2. Hereupon the followers t slide upon the cams r, and the rods s move in the sleeves it, because an oscillation thereof takes lace about the pivots i. If now the crossbar moves into the terminal position indicats at M, Fig. 2, then the ring 1), placed adjustably upon the shaft 1, strikes with its projection against the protective plate a, whereby the turning of the shaft Z and the motion of the lever system connected therewith are limited. As soon as the lap has been inserted by the cross-bar g the operative releases again the handle an. All the movable parts then immediately return into their original position in consequence of the action of the spring w, While the winding up of the lap proceeds further unhindered. It is obvious that the profile of the cams r is so chosen that the displacement of the crossbar is effected as suitably as possible. The most advantageous course for this crossbar is a combination of the curve drawn about the center of the winding-roll b and of another curve which has for its center the center of the laproller at its lowermost point. Both curves are connected by means of a third curve of very small radius. During its displacement the cross-bar should keep a regular but small distance from the outside of the Winding-rolls, as Well as from that of the lap-roller. Moreover, the said crossbar in its outermost position must not approach too near to the second Windin roll.

What I c aim is 1. In a Winding mechanism for cottonlaps, a protective device for the lap roller comprising an adjustable metal guard over said lap roller, an axle connected to said guard, a handle on said axle, lever mechan- 1SII1 at each end of said axle and a cross-bar attached to the ends of said lever mechanism, said device so arranged as to effect mechanically the insertion of the end of the lap under the lap-roller, substantially as set forth.

2. In a Winding mechanism for cottonlaps, a pair of Winding-rolls, a lap-roller adja cent to and between said rolls, a curved metallic perforated shield over said lap-roller, means for raising the shield concurrently with the la roller, and means for inserting mechanical y the end of the lap underneath the la roller.

3. n a Winding mechanism for cottonlaps, Windin rolls, a lap-roller, a shield above said la ro ler, a revoluble shaft on said shield, and mechanism adapted to turn said shaft, jointed levers at the ends of said shaft, a cross-bar attached to the ends of said levers guide-bars attached to the lower parts of sald levers adjustable followers on said guide bars, and curved cams adapted to guide the said cross-bar in a definite curved course and parallel to the la roller.

In testimony whereof I ave signed my name to this specification in the presence of two subscribing Witnesses.
